Bio:Sara Kingdom was a loyal member of the Space Security Service (SSS).

Notes:There is considerable debate as to whether Sara is a Doctor Who companion. Since the contract extended to her portrayer, Jean Marsh, never included an option to use her beyond the serial, "The Daleks' Master Plan"—and indeed because her sole use in comics is in a Dalek annual copyrighted by Terry Nation (rather than a Doctor Who product copyrighted by the BBC—this database takes the position that she was merely a featured guest star in an unusually long Doctor Who story.
